Abstract

Measurements of sediment flux on the windward slope of an isolated barchan using an array of 30 sand traps provide new data that can constrain models of dune dynamics. The data show that at low incident wind speeds, flux increases up the dune exponentially, whereas at higher wind speeds the increase with distance approaches linearity. The wind profile measurements demonstrate that conventional wind profiles, derived from anemometry on dunes, do not measure the part of the boundary layer that is significant for sediment transport
